Ten Worst Evolutionary Designs

I thought this was interesting, so here is a summary...

1. Blowholes - Why not gills?
   
2. Hyena Clitoris - It gets so hard and big it sometimes kills the babies during birth.
   
3. Kangaroo Teats - Yeah, let's crawl across the body from birth to get to this.
   
4. Giraffe Birth Canal - 5 feet up. Really?
   
5. Bird eating Spider Exoskeleton - A very fragile skeleton for a spider who cannot spin web.
   
6. Shark Fetus Teeth - Babies with teeth in the womb is just a bad idea.
   
7. Human Stomach - Why can't we digest plant matter?
   
8. Slug Genitals - Genitals that get stuck together and sometimes have to be chewed off!
9. Quadrupeds - Makes scratching your back very hard to do.
   
10. Narwhal Tusk - Indeed. A 9 foot useless tooth?
